Love, Ruby Valentine by Laurie B. Friedman (Carolrhoda Picture Books)

Deep in the heart of Heartland live Ruby Valentine and her trusty parrot Lovebird. Ruby's favorite day of the year is Valentine's Day--she loves to say "I love you" and make cards and treats to deliver to everyone in her town. But Ruby is so exhausted that she sleeps right through the holiday. Although Ruby is worried that she'll have to wait a whole year to tell everyone that she loves them, Lovebird convinces her to deliver her treats and messages of love even though they're a day late. To Ruby's surprise, no one minds. In fact, they're thankful for her sweet wishes and kind heart, leaving Ruby with the realization that every day is the best day to say "I love you"!
